I have Xcalar installed on an AWS EC2 cluster. How do I give access to the S3 buckets where I have all my data? Can Xcalar read directly from S3 or does the data have to be copied to local storage on the EC2s?

Just updated the above to reflect the change from Python 2.7 to 3.6 in Xcalar Design 1.3.0.

As of 1.3.0, /opt/xcalar/bin/ contains pip 3.6, the appropriate version for Python 3.6. As shorthand, Xcalar also added symbolic links pip & pip3, which point to pip 3.6. You can use any of those names to use the current version of pip.
